SPECIFICATION forming part of Letters Patent No. 664,744, dated. December 1960.

A li ati filed March 9, 1899. Serial No. 708.415. (N0 model.)

To all whom it may concern:

Be it known that I, FREDERICK JOHN HAR- in the district of Muskoka, in the Province of Ontario, Canada, have invented certain new and useful Improvements in Cylinder Printing-Presses, of which the following is a specification.

I My invention relates to improvements in oyl= are, first, to provide a delivery for the sheet by which it may be expeditiously taken from the machine without the aid of the impression-cylinder, andthereby effect an economy of time in the delivery of the sheet, and, further, so deliver the sheet that it will be deposited on the receiving-table with the printed side up; secondly, to provide a positive means for insuring the sheet being gripped and held onto the cylinder, and thereby effect a perfect register; thirdly, to provide a simple means for raising the impression-cylinder on its return movement, and, furthermore, an efiective throw-off for such cylinder, and, fourthly, to provide a simple, accurate, and very fine adjustment for the type-bed whereby the impression may be regulated to a nicety. These various objects are carried out by the construction of the machine arranged and operating as a whole and in detail as hereinafter more particularly explained.

For the purpose of clearly setting forth the construction of my machine and the advantages to be derived therefrom I have shown in which- Figure 1 isa perspective view of my printing-press complete. Fig. 2 is a longitudinal vertical section looking from the same side as Fig. 1. Fig. 3 is a longitudinal vertical section looking from the opposite side of the machine. Fig. 4 is a detail of the sheet-releasing trip. Fig. 5 is a perspective detail of the trip for operating the gripping-fingers to grasp the sheet from the feed-table. Figs. 5and 5 are end views of the cylinder, showing the position of the trip-fingers when the cylinder is at the delivery end and feed-table end, respectively, of its movement. Fig. 6 is a detail of the far cylinder-supporting reciprocating standard shown in Fig. 1. Fig. 7 is a detail of the means for reciprocating the ink-distributing rollers. Fig. 8 is a detail of the peripheral cam on the counter-shaft controlling the movement of the ink-distribut- B is the main driving-shaft of the machine,

which is provided with a driving gear-pinion B, which meshes with a gear-wheel O. on the counter-shaft G, from which latter shaft the principal moving parts of the machine derive their operation.

D is the feeding-table, which is pivotally supported at the front end of the machine by the pins din the frame, as indicated. The table D is wedge-shaped in cross-section, presenting a line edge near where the paper is delivered to the cylinder, as indicated.

E is the cylinder, which is hollow and is secured on across-shaft F, which is supported in the eccentric bearing-sleeves f, journaled in the sliding standards G. The outer ends of the shaft F extend into the blocksf, which are located in the slots h at the upper ends of the swinging arms H, which are-pivoted at the bottom on the cross-rod H, extending from side to side of the frame of the machine and outside of the same.

I is a pitman connected at one end to the gear-wheel C and at the opposite end to the swinging arms H. By means of this pitman I the arms are given their swinging movement backward and forward, thereby imparting to the cylinder its longitudinal reciprocating movement between the feeding-table Dand the delivery-table J. (Shown in dotted lines in 2.) Secured to the shaft F is a gearwheel K, which meshes with a rack k, attached to or forming a portion of one of the side bars of the frame of the machine.

L is the bed-plate, upon which the type, which is set in the usual manner in a chase, is placed, and 1 represents the tracks at the side of the bed-plate, which support the collars 2', 3, and 4: on the end of theinking-rollers 2, 3, and 4. The track 1 serves to keep the inking-rollers in a proper level position as they pass over the face of the type.

2 3 and 4 are the spindles of the inkingrollers, which are connected by the rods 4 and 5 at the ends of the spindles to the bar M, which is pivotally supported at the bottom on the ends of the cross-shaft N, suitably jou rnaled in the frame of the machine. Only one bar M is shown and its complement of rods 4 and 5. The rods 4 and 5 extend through the bent ends m of the bar M and are tensionally held by the spiral springs 6 and 7, abutting the upper bent end on and connected at the opposite end to the rods 4 and 5. The rollers 2, 3, and 4 derive their reciprocating movement over the bed by means-of the bar M, which is connected by the rodm 'to the lower end of the lever M which is pivoted at the top at M. The roller m is journaled on a stud on the lever intermediate of .by the cam-shaped groove 0 in which a roller m on the arm M moves. This through the pitman connection m causes the rollers to move from the position shown in Fig. 1 very rapidly, as the cam-groove has'a sharp throw. The-rollers 2, 3, and 4 then rest at the delivery end of the press during nearly half a revolution of the wheel 0, the rollers not beginning their return movement until the cylinder E has completed half of its return movement.

The ink-distributing roller 0 is supported in suitable bearings by means of the spindle O. A bevel pinion 0 is provided on the spindle at one end thereof, such bevel-pinion being engaged by a similar pinion 0 on the end of the spindle 0 which is journaled in suitable hearings in the frame. The opposite end of the spindle 0 is provided with a bevel-wheel 0 which meshes with a bevel gear-Wheel P, secured on the counter-shaft C. The bevel-wheel P is of snflicient diameter so as to drive the ink-distributing cylinder 0 sufficiently fast to properly and evenly conv ey the ink to the ink-rollers 2, 3,'and 4 when they are brought in contact wit-h it.

Q Q are the minor distributing-rollers,which abut'the major roller 0. The minor rollers Q and Q are provided with spindlesq and g, which extend through the reverse obliquelys'et slots r 'r in the end supporting-brackets R. It is necessary for the proper distribution of the ink that these minor rollers Q and Q begive'n an endwise movement alternately,

and in order to provide forthis I secure on one of the ends of the spindle the grooved collars g and g wardly-extending pins 4' and r (see dotted lines,) which extend into the grooves of the collars g and g respectively. One end of the rocking arm 1' has. pivotally connected to it the lever S, which is pivoted at s on the 7 frame and has a pin or roller 5 at the front end, which extends into a camgroove t of the cam-wheel T, secured to the counter-shaft C. (See Figs. 2 and 8.) By means of this peripheral cam-groove t of thecam-wheel T r it will be seen that the lever S is rocked on its pivot,.angl= its opposite end conveys alike rocking motion to the rocking bar 0 and consequently a reciprocating motion alter.

iiat-el'y in opposite directions to the minor rollers.

U is an intermediate minor ink-roll'er,.wh-ich is supported in crotches on the end of the arms V, pivoted in the bracket u at each end 4 of the ink-fountain.

W is the lowermost ink-roller, whichis in the fountain itself and upon which normally rests the intermediate roller U, which itself 7 normally is free of the major roller 0.

X is the bot-tom plate of the fountain, which is supported at one edge by the side of the fountain and at the opposite edge by alongitudinal bar at and set-screws 0c,.exten-ding through the bars, whereby such plate is'adjusted to any desired position in relation to the roller. The ink is held immediately above the plate X. The roller U is provided with a spindle 16, upon which it rotates, and th roller W with a spindle w.

In order to provide for the turning of the bottom roller W in the fountain, so as to feed loo 5 no 7 The upper n, secured to the shaft N, and at the opposite end having a bolt extending through the' slot '0 of the arm 1), the end of the bolt being provided with a small handle y, whereby the position of the connection ofthe link Y to the arm 4; may be veryquickly changed without the necessity of using a wrench, so that the throw of the arm, and consequently of the pawl, may be regulated to a nicety.

As the inking-rollers are moved through the pivoted bar M and mechanism hereinbefore described it will be seen that upon every such swinging movement the motion will. be communicated, through the arm n, link Y, and arm 2; and pawl o and ratchet-wheel 12 to the ink-roller, thereby serving to turn it intermittently. The cam-shaped projection 7 To the bottom of the bracket R, I secure a .7 bar r and pivoted atthe free end thereof the 7 rocking bar r which is provided with upi will also be raised, so as to pass beneath the arm V, and thereby intermittently raise the ink-roller U, journaled in the arms, from contact with the lower roller into contact with the major roller 0, thereby carrying the ink to the latter roller.

In order to adj ust the bed-plate L to a nicety, I provide at each end thereof the wedgeshaped bars Z, which rest upon theinwardlyprojecting ribs a at the interior of the frame and extend into correspondinggrooves at the outer edges of the bed-plate.

In order to adjust the bars Z, I secure on the end a collar 1*, within which extends the spindle Z which is provided with an ordinary annular groove, into which extends a pin from the collar, this being an ordinary construction and utilized in order to permit rotation of the spindle.

The spindle l is threaded at the outer end and provided with ahand-wheel Z and a looking hand-wheel Z and by means of the handwheel Z the bed-plate L may be raised and lowered as desired and with a very fine adjustment, so that the impression may be regulated to a nicety.

The feeding-table D-is provided with gagefingers Z, held on the cross-rod e, which is bent at the end into arms a, pivoted at e at each side of the table upon the brackets 53. A rod zi, supported in suitable guides 25, extends underneath the front end of the arm and downwardly, as shown, being bent at the lower end, so as to extend over the cam 2 secured on the counter-shaft O. The cam 5 is provided with a drop Z7. The spring 2 rests upon the front ends of the arms 2" at the top. It will thus be seen that as the shaft 0 and cam revolve in the direction indicated by arrow the gage-fingers will be forced down, so as to stop the paper, and when the end of the rod falls over the drop 2 will permit of the paper being grasped by the gripping-fingers of the cylinder E, the connection of which I shall presently describe, as the gage-fingers are then raised.

I have hereinbefore described that the shaft F is journaled at each end in the eccentric sleeves fin the standard G. Such standards Gslide upon the Ways G.

I shall now describe the manner in which the paper is fed and wound upon the cylinder preparatory to being printed and carried to the delivery gripping-fingers, whereby it isremovedontothedelivery-table. (Shownin dotted lines at the lefthand side of Fig. 2.) The cylinder E is a hollow cylinder having the ends secured to the shaft F and is provided with a longitudinal opening e, extending from end to end thereof, and end slots 6 and 6 E is the gripping-bar, which is provided with a series of gripping-lingers curved in form and having the edge normally resting and extending over the edge of the opening 6. The cylinder E is shown in its normal po sition in proximity to the table. The gripping-bar E is provided at each end with the pins 6 and 6 which extend through the slots e and 6 respectively.

6 and e are arms pivoted outside the ends of the cylinder E upon the rod e which extends through the cylinder. The pins e and e extend through the slots 6 and e in the arms 6 and 6 It will be noticed that both arms are substantially L-shaped and that the arm a is provided with an extension from which projects outwardly a pin e 8 is an arm pivoted on the cross-rod 9 and provided with an inwardly-extending end 10, which is designed to coact in the manner hereinafter described with the pin 6 11 is an arm secured to the same rod andprovided with an inclined end 12, which is reversely inclined as to direction of rotation to that of the inclined end 10.

The gaging fingers Z, hereinbefore described, are so timed to operate to raise to allow of the sheet to be grasped when the cylinder E revolves around into the position shown in full lines in Figs. 1, 2, 3, and 4 in order to connect the sheet to the cylinder that it may be wound around the same and printed as the cylinder traverses from the feed-table to the delivery-table. The gripping-fingers therefore have to be raised in order to allow the edge of the sheet fed to extend beneath them, so that the fingers may be dropped down upon the edge of the sheet. To raise the fingers and to allow of them to drop, the mechanism hereinbefore described is utilized, which operates as follows: As the cylinder continues to rotate in the direction indicated by arrow and approaches the feed-table the pin e on the end of the arm e mounts the inclined end 12 of the arm 11, thereby throwing the pins a and e on the ends of the gripping-bars and extending through the slots in the arms (2- and e upwardly, thus causing the gripping-fingers to raise from the cylinder and pass over the edge of the sheet. When the pin 6 has passed over the inclined end 12, the arm 6 drops, thereby allowing the pins 6 and e to recede in their respective slots 2 and e and the gripping-fingers to drop upon the edge of the sheet. 'At this juncture the cylinder starts to rotate in the opposite direction to that indicated by arrow in Figs. 5 and 51*, carrying with it the sheet of paper from the feeding-table, which winds around the cylinder until the cylinder has made one revolution in approaching the opposite end of the bed. At this juncture the pin e in the slot will strike and rise upon the inclined end of the arm 8 and mount into the position shown in Fig. 5 and then drop. The

grasped by the delivery-fingers, which I shall presently describe. \Vhen the cylinder has reached the limit of its stroke, as indicated, the pin 6 passes underneath the inclined end i 10 of the arm 8, and consequently does not affect the grippingbar, and the cylinder finally reaches the forward limit of itsstroke in proximity to the feed-table, whereupon the-same operation is repeated continuously during the process of printing.

In order to insure of the gripping-fingers dropping after being released upon each raising,- I provide a pair of helical springs 13, extending over the outer side of the grippingbar and secured at the opposite end to the shaft. As the cylinder rotates and arrives at the position shown in dotted lines in Fig. 2 it is necessary to hold the sheet up away from the periphery of the cylinder in order that such sheet may be grasped by the deliveryfingers, and in order to allow of this I provide a cross-bar 14 with upwardly-extending fingers 15 and downwardly-extending arms 16 at the end, which project through the bottom of the cylinder and are designed to come in contact with the track, so as to raise the fingers at this juncture, and consequently the sheet. It may be stated that I of course arrange these fingers directly underneath the gripping-fingers, as otherwise the sheet would be punctured.

In order to deliver the sheet when it has been brought by the cylinder and grippingfingers forward into proximity with the end ofthe bed of the machine and released by such gripping-fingers, I provide the following mechanism:

17 is a rock-shaft secured in the bracket extensions A of the frame.

18 represents arms secured to the ends of the rock-shaft and extending normally above the level of the delivery-table in an oblique direction, as indicated.

19 is a cross-rod connecting the of the arms 18.

20 is the lower gripping-bar, which is provided with a series of fingers 21 and the jourupper ends nal-rings 22, one of which is provided with a projection 23, which is designed to come in contact with a projection 24 on the collar 25 to limit the fall of the fingers. I

26 is the upper gripping-bar, provided with a series of fingers 27 and journaled on the rod 19 by the end rings 28.

29 is a spring encircling the rod 19 and secured at one end to the same and having the opposite end extending over the gripping-bar 26, so as to have a normal tendency to force the gripping-fingers 27 downwardly.

30 is a spring on the rod 19, secured at one end thereto and having the opposite end extending under the gripping-bar 20, the normal tendency of the springbeing to force the gripping-bar and the fingers 21 thereof upwardly.

27 and 21 are the end fingers, which are tending under a pin 32.

provided with laterally-extending pins 27 and 21 respectively.

31 is a rod connected to the finger 21 and extending down in suitable bearings. opposite the arm 18, the lower end being bentandexare being brought forward-to grip the edge of When the arms 18 the sheet by the mechanism, as hereinafter described, the lower bent end of the arm 31 is free from the pin 32; but when the upper end of the arm has reached the limit of its rearward stroke the bent end of the rod 31 7 contacts with the pin 32, thereby pulling down the finger 21 and releasing the sheet and allowing it to drop upon the delivery- 7 7 Q table. The arms 18 are connected by therod 33 to the lower end of the lever 34, which is pivoted at the top at-35 on the frame and is Z provided intermediately with a roller 36, which works in a cam-groove 37 in the opposite gear-wheel C. such that the arms 18 are caused to rest for The shape of. this camis a considerable period of the rotation of the wheel 0, which period is that occupied by the traversing of the cylinder from the point shown in dotted lines to the feeding-tableand 1 The remaining 7 back again to such ipoint. portion of the cam operates upon the roller 36, so as to bring the sheet-delivery fingers toward the cylinder when it reaches the dotted position and then bring it back again The shape of the cam 37, however, is such that the delivery-fingers travel at a uniform V 1 rate with the cylinder to the extreme end of the rearward movement of such cylinderv or the fingers to grasp the sheet as well as to.

open the fingers to release the sheet. In order to efiect this, it will be noticedthat Ipro vide a separating-cam 38, attached to or forming part of the supporting-rollers 39, which a i These rollers 39 r at each end, as the cylinder and .the shaft i thereof revolve, of course necessarily supportf run on the upper tracks G the cylinder during its movement across the 7 bed of type, and the cam 38 is so arranged and timed that when the grippingfingers meet the cylinder this cam 38 will pass be tween the pins 21 and 27 thereby separatthe edge of the paper. As soon as the. cam

12b ing the fingers and allowing them to straddle V has passed between the pins 27 and 21 the *7 fingers 27 and 21 are forced by their springs together, so that the edge of the sheet is securely gripped, whereupon it is carried away r by the rearward movement of the sheet-delivery device hereinbefore described.

I find it preferable to provide a pressure-j r 39 t is designed to press against the edge of the f roller g near each end of the cylinder, which printed sheet of paper and prevent it from falling back from the cylinder during the period between when the edge of the sheet is loosened by the gripping-fingers on the cylinder and the time it is being grasped by the sheet-delivery grippingfingers. These rollers are secured on the ends of the arms g, pivoted on the bearing-standard G, and are held up to the cylinder by the springs 9 It will be noticed,as herein before described, that the spindle F of the cylinder is supported at the ends in the eccentric collars or sleeves fin the bearing-standards G. It is necessary in the backward movement of the cylinder after having brought the paper over the type to receive the impression to raise such cylinder in order to escape the type. In order to effect this, I provide projecting arms 40, having lateral extensions 41,through' which extends set-screw 42. Upon one lateral extension 41 is formed a bearing 43, which receives the curved end of the rod 44, which extends through the guiding-lug 45 on the side of the machine and is provided with an end stop 46. As the cylinder is caused to move toward the delivery end of the bed after the printing has been effected, the stop 46 coming in contact with the lug 45 pulls back upon the arm 40, thereby turning the sleeve or collar fin its bearing in the standards G, so that the long radius of the eccentric is lowermost, thereby raising the cylinder in its movement clear of the bed, in which position it will remain as the retrograde movement is being effected. At near the limit of the retrograde movement, however, the arms 40, which are now in a substantially vertical position,strike against the pivoted rocking detents 47, which are held rigidly against the pins 48, and thereby knock the arm 40 backward again into its initial position shown in Figs. 1 and 6. This operation is repeated upon each reciprocating movement of the cylinder.

In order to provide a means whereby should one sheet be missed through the fault of the attendant of the machine, I provide the following simple device, or What is technically known as the throw-01f, in order to raise the cylinder clear of the type and prevent it printing on the tympan or pad on the cylinder.

49 represents catches secured on each end of the rod 50, which is suitably pivoted in the side bars of the feed-table, as indicated. The catch 49 is provided with a weighted handle 51, and the rear end of the catch is designed to be brought into engagement with the notch 52 in the upper end of the rocking detent 47 when a sheet has been missed. The result is that the arms 53, forming part of the eccentric sleeves f at each end of the spindle F, come in contact with the bottom end of such rocking detents, and thereby, as such rocking detents are locked, the arms 53 are turned downwardly as to direction of movement of the cylinder,so as to throw the longer radius of the eccentric sleeves flowermost, and thereby raise the cylinder above the height of the bed, so that such cylinder when no sheet is on it will pass in such elevated posit ion backward and forward to its initial position again without any printing being efiected.

It is of course to be understood that when the arm 53 is tilted it will be tilted su-fficlently so that it will pass under the rocking detent. As the arm 53 moves with the cylinder in its movement to the feeding-table again it will again pass under the lower end of the rocking detent at each side; but the arm 40, whichis now raised, will strike against the now locked rocking detent, whereupon the arm 40 on each side will be lowered into its initial position, ready for the next forward movement of the cylinder,'which is thereby lowered, ready to give the impression. The catch 49 may be of course raised from engagement with the notch at the top of the rocking detent at any time after the cylinder has passed such detent in its movement toward the delivery-table.

In aprinting-press,the combination with the feeding-table, of the gaging-fingers located opposite the inner end of the table, the rods having bent ends pivotally supported, the springs normally pressing on the bent ends or arms, so as to hold up the gaging-fingers and means for intermittently overcoming the pressure of the springs, so as to press the fingers to the edge of the table as and for the purpose specified.
